In Canada April 6, 1932 2 Claims.

This application is a continuation in part of my application filed December 18, 1930, Serial No. 503,278.

The invention described and claimed herein relates to blankets or covers for stoves especially adapted for application upon the tops of stoves or other heating devices to insulate and retain the heat and provide a better distribution of heat to the ovens and other desired portions of the l0 stoves and has for the primary object, the provision of a device of the above stated character which will be fire-proof, durable and easy to apply and remove from the stove when desired.

An object of the invention is the provision of a device of the kind indicated embodying a filler of heat insulating material and a covering member for the same consisting of a metallic frame of loose construction which not only provides for expansion and contraction without loss of shape but also provides for the device finding a firm seat on top of the stove irrespective of irregularities in the latter.

A further object of this invention is the provision of a cover or blanket for stoves of the above stated character which is simple, durable and efficient and which may be manufactured and sold at a comparatively low cost.

With these and other objects in view, this invention consists in certain novel features of construction, combination and arrangement of parts to be' hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which:

Figure 1 is a fragmentary perspective view illustrating a stove with a cover or blanket applied thereto and constructed in accordance with my invention.

Figure 2 is a plan view partly broken away illustrating the blanket or cover.

Figure 3 is a sectional view taken on the line 3--3 of Figure 2.

Figure 4 is a fragmentary plan View illustrating one section of the frame.

Figure 5 is a similar view illustrating a companion section of the frame to that shown in Figure 4.

Figure 6 is a sectional view taken on the line 6 6 of Figure 2.

Referring in detail to the drawing, the numeral i indicates in its entirety a blanket or cover to be positioned over the top of a stove 2 for the purpose of retaining heat therein which usually radiates from the top of a stove, thus causing the retained heat to more effectively heat the oven 3 and other desired portions of the stove. This cover is preferably made of aluminum, because the same presents a certain amount of brilliancy, is easily cleaned, is of a minimum weight, and when heated will not throw out excessive heat in a dwelling, presents no sharp edges, is free of rust and is easily worked. The

device as shown in Figure l will also have considerable advantage in hot weather as the heat 1;; radiating from the top of the stove will be confined Within the stove and the other parts thereof so as not to radiate directly upwardly.

A ller 4 of considerable thickness and co-nstructed from heat resisting or insulating and 15 noninflammable material is mounted in a frame 5 and has one face covered by a metallic plate 6 disposed uppermost when the device is positioned upon the stove and the opposite face covered by a plate 'l of heat resisting material and prefer- 20 ably a composition known as Welders millboard. The plates 6 and l as well as the filler Il are mounted within the frame 5.

The frame is of a flanged type as shown in Figure 3 having a groove 8 in the margin thereof 25 which provides an efficient finger grip for permitting a person to obtain a firm hold upon the cover or flange when desiring to place upon or remove the latter from the stove` The frame is constructed of a plurality of sec- 30 tions cross-sectionally W-shaped, the side and end members having their ends bevelled as shown at 9 and provided adjacent said ends with slots l) to receive fasteners Il which are adapted to permit the sections to have sliding movement 35 relative to each other for the purpose of compensating for the expansion and contraction of the metals involved in the construction of the blanket or cover. The frame sections, while W-shaped in cross-section, are generally in the 40 form of channels and the two inner legs of the W are formed by the web portion of the channel, the two outer legs constituting parallel anges. The linger gripping space is formed by the converging faces of the two inner legs but the apex 45 of the angle which they form acts as an abutting edge for the ller 4, While the lower plate l and upper plate 6 which encase the filler are received in the spaces defined by the flanges and the adjacent inner leg portions of the W formed 50 in the web of the channel. This arrangement provides for the maintaining of the spaced relation of the plates, so that the filler may be relieved of pressure due to their weight with the consequent tendency to compress the filler with consequent loss of efciency as a heat insulating medium.

What I claim is:

1. A blanket for flat top stoves comprising a rectangular frame composed of a plurality of cross-sectionally W-shaped channel sections of which the two inner legs of the W-shaped conformation are formed from the web of the channel and the two outer legs constitute parallel flanges of the channel, the channel sections being disy posed on their sides to arrange the flanges horizontally but inwardly directed, fasteners connecting the sections together at their extremities, plates mounted inthe channel sections and engaged at their perimeters in the crotches formed by the flanges of the channels and the adjacent inner leg portions of the web of the channels, and a ller of heat insulating material interposed between the plates.

2. A blanket for ilat top stoves comprising a rectangular frame composed of a plurality Yof cross-sectionally W-shaped channel sections of which the two inner legs of the W-shaped conformation are formed from the web of the channelI plates mounted in the channel sections and engaged at their perimeters in the crotches formed by the flanges of the channels and the adjacent inner leg portions of the web of the channels, and a ller of heat insulating material interposed between the plates and abutting the apex of the angle formed by the inner leg portions of the webs of the channels.
